AVG Free will not uninstall

I've downloaded and run AVG Clear, but the problem is exactly the same.  There are still alot of AVG titled folders within appdata, so all traces of AVG have not been removed by the Clear tool. I'm still unable to install any other anti-virus, even AVG which is the one I want to use.  Desperate for a fix that works.
Cheers,

Hi,
I'm running Win10 Anniversary update edition with all current updates installed. I've uninstalled AVG Free using the Windows uninstaller and rebooted the machine to complete the uninstall. I then viewed my installed programs list and AVG Free still appeared in it, so I clicked the uninstaller again and I was told that AVG Free appeared to already be uninstalled and would I like to remove it from the installed programs list.  So I said "yes", and it disappeared.  Now when ever i go to install a new antivirus product, or even try to re-install AVG Free again I'm told that I cannot complete the installation as AVG Free is already installed on my computer.  I have downloaded and run the AVG uninstaller, and it appears to have worked, going through all the motions and asking me to re-boot, but when I try to install any other anti-virus product (even AVG) I continue to get the message as detailed above.  I mentioned this to a friend who reported that he had the same problem and now has to rely on Windows Defender, a state that I do not want to be in. 
Any help would be greatly appreciated.
